World-Class Computational Fluid Dynamics for aerospace applications

ICON Aerospace Aero-Acoustics CFD offers an appealing unlimited simulation option to some of the world’s largest Aeronautical manufacturers and their suppliers. The exceptional design, optimisation and evaluation capabilities it provides will help you deliver measurable improvements in both external and internal aero-acoustics. Trusted and proven over decades, ICON has delivered CAE simulations in many different areas of expertise. This includes but is not limited to design and optimisation of aircraft cabins, rocket launchers external aerodynamics evaluation, ice accretion simulation, etc.

ICON Aerospace Aero-Acoustics CFD will help you address noise pollution. For example, flow induced noise generated by parts and subsystems of the aircraft ventilation system is increasingly important in defining comfort for aircraft passengers and cabin crews, as well as for ground crews. Such noise can be generated, for example, by flow through parts of the air generation units (pack), through mixing and recirculation devices, through final air distribution devices (cabin air outlets), fans, etc.

The big difference is that we are engineers first, not just expert coders with exceptional software. ICON engineers are fully integrated into the working environment of businesses through on-site support activities. This ensures that a broad knowledge of the technical objective of the analyses is also supported by experience of how new designs will be integrated within the aircraft development process as a whole. Not every CFD software provider is willing or able to do this.
